Description

Technical Field

[0001] The utility model relates to the technical field of flat parking locks, in particular to a flap assembly and a parking lock. Background Art

[0002] At present, with the development of my country's economy, private cars have entered thousands of households, but the corresponding number of parking spaces is seriously insufficient, causing the problem of parking difficulties in major cities. Usually, in order to protect the interests of car owners with fixed parking spaces, people have invented various parking locks, among which flat locks are increasingly used in parking locks due to their convenient lifting and low cost.

[0003] Existing flat plate locks usually consist of a flap and a driving mechanism that drives the flap to flip or lift. When the flat plate lock is opened, the flap is raised to prevent external vehicles from entering the parking space or prevent vehicles in the parking space from leaving the parking space; when the flat plate lock is closed, the flap is lowered, and vehicles can press over the flat plate lock to enter or leave the parking space.

[0004] The flap is formed by bending a sheet metal plate. Specifically, the flap includes a surface shell in contact with the car, grid-shaped reinforcement ribs arranged under the surface shell, and a frame arranged outside the reinforcement ribs. The overall structural strength is poor, and the sheet metal structure is easily deformed and damaged. In addition, the reinforcement ribs and the surface shell are welded, which is not only bulky and complex to process, but also has a rough surface and is prone to rust. Since the flap may be subjected to external forces such as rolling or collision by vehicles when it is raised or dropped, it is easy to deform or be damaged when the strength of the flap is low, which will cause the locking function of the flat lock to fail.

[0005] Therefore, there is an urgent need for a flap and a parking lock to overcome the above-mentioned defects. Utility Model Content

[0006] In order to overcome at least one of the defects of the prior art described above, one of the purposes of the present invention is to provide a flap assembly, which has high strength and rigidity, can withstand external force impact, and has a light overall mass.

[0007] The second purpose of the utility model is to provide a parking lock, the flip assembly of which has high strength and rigidity, can withstand external force impact, and has a light overall weight.

[0008] One of the technical solutions adopted by the utility model to solve the problem is:

[0009] A flap assembly, used for a parking lock, includes a flap body, the flap body includes a pressure plate and a support plate arranged opposite to each other, a cavity is formed between the pressure plate and the support plate, a support frame is provided in the cavity, the support frame extends along the length direction of the flap body, and the two ends of the support frame are respectively connected to the pressure plate and the support plate.

[0010] The flap body provided by the utility model can reduce the weight of the flap assembly by arranging a cavity in the flap body, so that the driving assembly of the parking lock can drive the flap assembly to flip with less power, thereby reducing the performance requirements of the driving assembly. The support frame is arranged in the cavity to support the flap body, enhance the strength and rigidity of the flap body, reduce the degree of its deformation, and thus improve the pressure bearing performance of the flap body.

[0011] In addition, the support frame is extended along the length direction of the flap body, and the two ends of the support frame are respectively connected to the pressure plate and the support plate, which is convenient for the support frame, the pressure plate and the support plate to be integrally formed, thereby reducing processing time; when the flap body is under pressure, the support frame can evenly disperse the pressure, thereby ensuring that the flap body is not easily damaged.

[0012] Furthermore, the support frame, the pressure plate and the support plate are an integrally formed structure.

[0013] Therefore, the flap body can be manufactured without welding, the manufacturing process is simple, the processing time is reduced, and the production efficiency is improved.

[0014] Furthermore, at least two of the support frames are disposed in the cavity, and at least two of the support frames are spaced apart along the width direction of the flap body.

[0015] In this way, the connection area between the supporting frame and the pressure plate can be increased, so that the pressure borne by the pressure plate is evenly distributed to each supporting frame, preventing stress concentration.

[0016] Furthermore, two adjacent supporting frames are close to or separated from each other at one end close to the pressure plate, and are separated from or close to each other at one end close to the supporting plate.

[0017] As a result, multiple triangular or trapezoidal structures are formed between the support frame and the flap body, which can enhance the strength and rigidity of the flap body; when the support frame is subjected to force, it can further tilt along the pressure direction, and use the slight deformation of the support frame to absorb excessive pressure loads, which can further reduce the deformation of the support frame and the flap body.

[0018] Furthermore, the pressure plate includes a pressure plate section and a connecting plate section, and the connecting plate section connects the pressure plate section and the support plate; the connecting plate section and the pressure plate section are connected in an arc shape.

[0019] In this way, sharp angles can be avoided between the contact surface of the flap body and the vehicle, thereby preventing the chassis of the vehicle from being scratched.

[0020] Furthermore, the pressure-bearing plate section includes a first pressure-bearing section and a second pressure-bearing section, the first pressure-bearing section is arranged between the connecting plate section and the second pressure-bearing section; the first pressure-bearing section gradually inclines upward along an end close to the connecting plate section to an end away from the connecting plate section; the second pressure-bearing section gradually inclines downward along an end close to the first pressure-bearing section to an end away from the first pressure-bearing section.

[0021] As a result, the flap assembly can be tilted from low to high at the first pressure-bearing section to form a guiding surface, which is helpful in guiding the vehicle to climb forward or backward over the flap assembly.

[0022] Furthermore, the flap body is provided with a first mounting hole for installing the driving shaft of the parking lock at a corresponding position at the connection between the first pressure-bearing section and the second pressure-bearing section, and the flap body is provided with a second mounting hole for installing the rotating shaft of the parking lock at a corresponding position of the second pressure-bearing section. The central axis of the first mounting hole and the central axis of the second mounting hole are parallel to each other and extend along the length direction of the flap body.

[0023] Therefore, the cavity is divided into multiple cavity segments by the supporting frame along the width direction, and these cavity segments extend along the length direction of the flap body. Therefore, the cavity segments can be used as axial holes for installing the rotating shaft and the driving shaft, so that the space of the cavity can be fully utilized and the overall volume of the flap assembly can be reduced.

[0024] Furthermore, a plurality of anti-slip structures are provided on the pressure-bearing surface of the pressure-bearing plate segment facing away from the cavity.

[0025] Thereby, it is possible to prevent the vehicle from slipping when climbing the flap body.

[0026] Furthermore, a groove is provided on a side of the support plate facing away from the cavity.

[0027] Thus, when the flap assembly is lowered, the groove at the bottom of the flap body can accommodate sand or debris on the ground or the fixed seat, so that the flap assembly can be lowered into place without being affected.

[0028] Furthermore, the flap assembly also includes an end cover, which is arranged at the end of the flap body; a protruding connecting portion is provided on the side of the end cover facing the cavity, and the protruding connecting portion is used to extend into the cavity for fixed connection with the flap body.

[0029] Thus, the end cover can support the pressure plate through the protruding connection portion; and the bottom of the end cover can support the flap body together with the support plate of the flap body, thereby enhancing the strength of the flap body.

[0030] Furthermore, the bottom of the end cover is flush with at least a portion of the bottom of the flap body.

[0031] In summary, the flap assembly provided by the utility model has the following technical effects:

[0032] 1) The cavity is provided in the flap body to reduce the weight of the flap assembly, so that the driving assembly of the parking lock can drive the flap assembly to flip with less power, thereby reducing the performance requirements of the driving assembly;

[0033] 2) Providing a support frame in the cavity to support the flap body can enhance the strength and rigidity of the flap body, reduce the degree of its deformation, and extend the service life of the flap body;

[0034] 3) The support frame extends along the length direction of the flap body, which facilitates the integrated molding of the support frame, the pressure plate and the support plate; at the same time, when the flap body is subjected to a large impact load, the support frame can disperse the pressure along the length direction to prevent stress concentration and enhance the pressure bearing capacity of the flap body.

[0035] The second technical solution adopted by the utility model to solve the problem is:

[0036] A parking lock comprises a fixing seat and the flap assembly as described above, wherein the flap assembly is rotationally connected to the fixing seat via a rotating shaft.

[0037] Therefore, the parking lock with the above-mentioned flap assembly has strong pressure-bearing capacity and impact resistance. The driving assembly of the parking lock can drive the flap body to rotate around the rotating axis to realize the flipping of the flap body, thereby switching the locking state and unlocking state of the parking lock.

[0038] Furthermore, the parking lock also includes a driving assembly, which has a driving arm, and the driving arm is rotatably connected to the flap assembly through a driving shaft; when the driving assembly drives the driving arm to move, the driving arm drives the flap assembly to rotate around the rotating shaft through the driving shaft.

[0039] Thus, the parking lock can drive the flap assembly to rotate around the rotation axis through the driving arm of the driving assembly, thereby realizing the flipping movement of the flap assembly.

[0040] The parking lock provided by the utility model can reduce the weight of the flap assembly by arranging a cavity in the flap body, so that the driving assembly can drive the flap assembly to flip with less power, thereby reducing the performance requirements of the parking lock on the driving assembly. The supporting frame is arranged in the cavity to support the flap body, enhance the strength and rigidity of the flap body, reduce the degree of its deformation, thereby improving the pressure bearing performance of the parking lock and increasing the service life of the parking lock.

[0050] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0051] Embodiment 1

[0052] See also Figures 1 to 3 The utility model discloses a flap assembly, which can be applied to a parking lock 2 to restrict vehicles from entering or exiting a parking space. Specifically, the flap assembly includes a flap body 1, and the flap body 1 includes a pressure plate 12 and a support plate 13 that are arranged opposite to each other, and a cavity 11 is provided between the pressure plate 12 and the support plate 13. A support frame 14 is provided in the cavity 11, and the support frame 14 extends along the length direction of the flap body 1, and at the same time, the two ends of the support frame 14 are respectively connected to the pressure plate 12 and the support plate 13.

[0053] On the basis of this structure, when using the flap assembly of the utility model, the flap assembly can be directly installed on the ground of the parking space, or installed on the fixing seat 22 of the parking lock 2, such as Figure 5 As shown, the driving assembly 21 on the parking space lock 2 can drive the flap assembly to flip, so that the flap assembly is raised to a locked state for locking the parking space, or is lowered to an unlocked state for unlocking the parking space.

[0054] It should be noted that the parking lock 2 is a locking device installed on the parking space, which can protect the interests of the car owner with a fixed parking space or reduce the human management cost of the paid parking space. The parking lock 2 commonly found on paid parking spaces is in an unmanned, automatic control mode. When no car is parked, the parking lock 2 is unlocked, and the flap assembly is lowered. Figure 4 As shown, it does not affect the normal passage of pedestrians. When a car enters the parking space, the parking lock 2 automatically recognizes and raises the flap assembly to restrict the movement of the car, such as Figure 5 As shown, the car owner needs to scan the code to pay, and then the parking lock 2 will be unlocked before the car can leave.

[0055] The vehicle will press over the parking lock 2 when entering or exiting the parking space. If the flap assembly is not strong enough, it will be easily deformed and damaged when subjected to cyclic pressure or local concentrated pressure, thereby causing the locking function of the parking lock 2 to fail. In order to ensure the structural strength of the flap, most existing flap assemblies are made of metal plates; however, the weight of the metal flap assembly is too heavy, and the drive assembly 21 needs to use a large power to drive the flap assembly to flip, that is, the performance requirements of the drive assembly 21 are higher during the process of lifting and lowering the flap assembly.

[0056] Therefore, the utility model reduces the overall weight of the flap assembly by setting a cavity 11 in the flap body 1, so that the driving assembly 21 can drive the flap assembly to flip with less power, thereby reducing the performance requirements of the driving assembly 21. At the same time, in order to ensure the structural strength of the flap body 1, a support frame 14 is set in the cavity 11, and the two ends of the support frame 14 are respectively connected to the pressure plate 12 and the support plate 13, which can support the pressure surface of the flap body 1, enhance the strength and rigidity of the flap body 1, and reduce the degree of its deformation. The pressure surface of the flap body 1 is the side of the flap body 1 that is away from the cavity 11.

[0057] Specifically, when the vehicle passes over the pressure-bearing surface of the flap body 1, the upper end of the support frame 14 is connected to the pressure-bearing plate 12, the lower end of the support frame 14 is in contact with the support plate 13, and the support plate 13 is in contact with the ground or the fixed seat 22, the weight of the vehicle can be borne and dispersed by the support frame 14, so that the pressure-bearing structure of the flap body 1 is more stable. That is, the support frame 14 can improve the stress distribution of the flap body 1 when it is subjected to external force, thereby avoiding or reducing the deformation of the flap body 1. Therefore, the support frame 14 can improve the durability and service life of the flap body 1.

[0058] It is worth noting that the support frame 14 extends along the length direction of the flap body 1, which facilitates the integral molding of the support frame 14 with the pressure plate 12 and the support plate 13, thereby reducing the processing time; and when the flap body 1 is subjected to pressure, the support frame 14 can evenly disperse the pressure along the length direction of the flap body 1, thereby ensuring that the flap body 1 is not easily damaged. In addition, the cavity 11 is surrounded by the pressure plate 12 and the support plate 13, which can prevent external sand, gravel, debris or rainwater from entering and accumulating in the cavity 11, thereby ensuring that the weight of the flip assembly is relatively light.

[0059] In this embodiment, Figure 3As shown, the cavity 11 can be formed by the pressure plate 12 and the support plate 13 of the flap body 1, and the two ends of the support frame 14 are respectively connected to the top wall and the bottom wall of the cavity 11, and the flap assembly is abutted by the bottom plate of the flap body 1 and the ground or the fixed seat 22 of the parking lock 2 when in use. In some embodiments, the cavity 11 can also be formed by the pressure plate 12 and the end cover 16 of the flap body 1, without the support plate 13; or the cavity 11 can also be formed by the pressure plate 12 of the flap body 1 being concave on its bottom surface, without the support plate 13 and the end cover 16. At this time, one end of the support frame 14 is connected to the top wall of the cavity 11, and the cavity 11 has a downward opening, and the other end of the support frame 14 is abutted against the ground or the fixed seat 22 of the parking lock 2 when the flap assembly is in use. When the flap body 1 is provided with a cavity 11 without the support plate 13 and / or the end cover 16, the weight of the flap assembly can be further reduced.

[0060] In this embodiment, if Figure 3 As shown, the support frame 14, the pressure plate 12 and the support plate 13 are an integrated structure, which enhances the overall structural strength of the flap body 1. The flap body 1 is made of aluminum profiles.

[0061] Therefore, welding is not required during the manufacture of the flap body 1, the manufacturing process is simple, the processing time is reduced, and the production efficiency is improved; and the structural strength of the flap body 1 is guaranteed.

[0062] Further, see Figure 3 At least two supporting frames 14 are disposed in the cavity 11 , and at least two supporting frames 14 are spaced apart along the width direction of the flap body 1 .

[0063] Among them, arranging multiple support skeletons 14 in the cavity 11 can increase the connection area between the support skeletons 14 and the pressure-bearing plate 12, so that the pressure on the pressure-bearing plate 12 is evenly distributed to each support skeleton 14 to prevent stress concentration.

[0064] In this embodiment, the plurality of support frames 14 extend along the length direction of the flap body 1 and are alternately arranged in the width direction of the flap body 1. The width direction of the flap body 1 is the forward or backward direction of the wheels on the flap body 1.

[0065] In this way, the strength of the flap body 1 along the length direction can be enhanced, and the cavity 11 is divided into multiple cavity segments by the supporting frame 14 along the width direction. These cavity segments extend along the length direction of the flap body 1, so that the cavity segments can be used as axial holes for installing the rotating shaft and the driving shaft. After the rotating shaft and the driving shaft are installed in the cavity segments, the driving assembly 21 can drive the driving shaft to drive the flap assembly to rotate around the rotating shaft.

[0066] Furthermore, two adjacent support frames 14 are close to or separated from each other at one end close to the pressure plate 12 , and correspondingly, two support frames 14 are separated from or close to each other at one end close to the support plate 13 .

[0067] Among them, the two adjacent support frames 14 are gradually tilted from one end close to the pressure plate 12 to one end close to the support plate 13, and the tilt directions of the two are opposite. Then, when the ends of the two adjacent support frames 14 close to the pressure plate 12 are close to or separated from each other, and at the same time, the ends of the two adjacent support frames 14 close to the support plate 13 are separated or close to each other, the two adjacent support frames 14 and the top wall and bottom wall of the cavity 11 are jointly arranged to form a triangular, trapezoidal or quadrilateral structure.

[0068] It should be noted that the triangular, trapezoidal or quadrilateral structures are relatively stable and can prevent or reduce the deformation of the flap body 1. In particular, the triangular structure can further reduce the deformation of the support frame 14 and the flap body 1. The triangular hollow structure can also have a certain cushioning effect.

[0069] That is, the support frame 14 is arranged at an acute angle or an obtuse angle with the pressure plate 12 and the support plate 13. When the flap body 1 is subjected to a large external impact load, the support frame 14 is more likely to further tilt and deform along the pressure direction, thereby utilizing the slight deformation of the support frame 14 to absorb excessive impact loads, thereby ensuring the stability of the flap body 1 structure itself, and the support frame 14 is not prone to breakage. In contrast, when the support frame 14 is arranged at a right angle with the pressure plate 12 and the support plate 13, the pressure direction of the support frame 14 and the flap body 1 are consistent, and the support frame 14 cannot be deformed, resulting in hard contact between the support frame 14 and the flap body 1, reducing the buffering effect, and the flap body 1 is more likely to be damaged when subjected to a large impact load.

[0070] In addition, since the inclination directions of two adjacent support frames 14 are opposite, when the two adjacent support frames 14 are subjected to pressure in the pressure-bearing direction, the two adjacent support frames 14 have an inclination tendency in opposite directions, so that the deformation of the support frames 14 in two opposite directions can offset each other, thereby improving the pressure-bearing capacity of the support frames 14.

[0071] In this embodiment, Figure 3 As shown, the pressure plate 12 includes a pressure plate segment and a connecting plate segment 122 , and the connecting plate segment 122 is connected to the pressure plate segment in an arc shape; wherein the connecting plate segment 122 is used to connect the pressure plate segment and the support plate 13 .

[0072] On the basis of this structure, since the pressure plate 12 and the support plate 13 can be an integrally formed structure, specifically, during the production, an aluminum alloy plate can be rolled into a flap body 1 with a cavity 11 structure, and then the support frame 14 can be installed in the cavity 11; or a flap body 1 with a cavity 11 structure and a support frame 14 can be made through a casting process. At this time, the pressure plate 12, the support plate 13 and the support frame 14 are an integrally formed structure. The flap body 1 of this integrally formed structure is adopted in this embodiment, which will greatly improve the structural strength of the entire flap body 1 and enhance the rolling resistance and impact resistance of the flap body 1.

[0073] Among them, since the flap assembly will inevitably collide with the vehicle when in use, if the connecting plate section 122 is connected to the pressure plate section at a right angle, a sharp angle will be formed on the side of the flap body 1; then after the parking lock 2 lowers the flap assembly, during the process of the vehicle climbing from the side of the flap body 1 to the top of the flap body 1, the sharp angle on the flap body 1 can easily scratch the chassis of the vehicle.

[0074] Therefore, the arc-shaped connection between the connecting plate section 122 and the pressure plate section can avoid sharp angles on the contact surface between the flap body 1 and the vehicle, thereby preventing the vehicle from being scratched. In addition, the arc-shaped connection between the connecting plate section 122 and the pressure plate section can reduce stress concentration at the connection between the connecting plate section 122 and the pressure plate section, thereby increasing the pressure-bearing performance of the flap body 1.

[0075] It should be noted that the connecting plate section 122 can also be set as an arc-shaped plate section, so that the connecting plate section 122, the pressure-bearing plate section and the support plate 13 are all connected at an arc angle; when the flap assembly is lifted, it is not easy to scratch the chassis when the vehicle presses forward or backward over the flap body 1. In addition, when the connecting plate section 122 is set as an arc-shaped plate section, the side of the flap body 1 is curved, which makes it easier for the vehicle to climb over the flap body 1 from the side of the flap body 1.

[0076] Further, the pressure-bearing plate section includes a first pressure-bearing section 121 and a second pressure-bearing section 124, and the first pressure-bearing section 121 is arranged between the connecting plate section 122 and the second pressure-bearing section 124. The first pressure-bearing section 121 gradually inclines upward from one end close to the connecting plate section 122 to one end away from the connecting plate section 122; the second pressure-bearing section 124 gradually inclines downward from one end close to the first pressure-bearing section 121 to one end away from the first pressure-bearing section 121.

[0077] Thus, the flap assembly can form a guide surface by tilting from low to high in the first pressure section 121, which is conducive to guiding the climbing vehicle to climb over the flap assembly. In addition, because the flap assembly gradually tilts the second pressure section 124 downward, guide surfaces are formed on both sides of the pressure section, that is, the first pressure section 121 and the second pressure section 124 both play a guiding role, which is conducive to the vehicle climbing forward or backward from both sides of the flap body 1 over the flap assembly.

[0078] Furthermore, the flap body 1 is provided with a first mounting hole 15 for mounting the driving shaft of the parking lock 2 at a corresponding position at the connection between the first pressure-bearing section 121 and the second pressure-bearing section 124, and the flap body 1 is provided with a second mounting hole 17 for mounting the rotating shaft of the parking lock 2 at a corresponding position of the second pressure-bearing section 124, and the central axis of the first mounting hole 15 and the central axis of the second mounting hole 17 are parallel to each other and extend along the length direction of the flap body 1.

[0079] Therefore, in this embodiment, the support frame 14 is extended along the length direction of the flap body 1, and a plurality of support frames 14 are arranged in the cavity 11, so that the cavity 11 is divided into a plurality of cavity segments along the width direction by the support frames 14, and these cavity segments are all extended along the length direction of the flap body 1, so that the cavity segments can be used to form shaft holes for installing the rotating shaft and the driving shaft. In this way, the space of the cavity 11 can be fully utilized and the overall volume of the flap assembly can be reduced.

[0080] In this embodiment, Figure 3 As shown, a plurality of anti-slip structures 123 are provided on the pressure-bearing surface of the pressure-bearing plate segment facing away from the cavity 11 .

[0081] Among them, the pressure-bearing surface of the pressure plate section facing away from the cavity 11 is the guiding surface, and the anti-skid structure 123 thereon can be an anti-skid protrusion or an anti-skid groove 131. The anti-skid protrusion or the anti-skid groove 131 can increase the contact area between the wheel and the guiding surface, thereby preventing the vehicle from slipping on the guiding surface of the flap body 1.

[0082] In this embodiment, Figure 3 As shown, a groove 131 is provided on a side of the support plate 13 facing away from the cavity 11 .

[0083] Specifically, the support plate 13 has a support surface on one side facing away from the cavity 11 , and the groove 131 can be formed by a portion of the support surface being recessed toward the cavity 11 ; or a boss can be provided on the support surface, and the groove 131 is formed around the boss.

[0084] On the basis of this structure, the parking lock 2 raises the flap assembly in the locked state and lowers the flap assembly in the unlocked state, and the flap assembly rests against the ground or the fixed seat 22 with the support surface of the support plate 13 when being lowered; during the period when the flap assembly is raised, debris or sand and gravel may be brought to the ground or the fixed seat 22 by vehicles or wind and other factors, and then the flap assembly may be affected by the debris and sand and gravel when being lowered and cannot be lowered into place, thereby causing the vehicle to collide with the flap body 1 that has not been lowered into place when entering or exiting the parking space.

[0085] Therefore, in this embodiment, a groove 131 is provided on the supporting surface of the supporting plate 13, so that when the flap assembly is lowered, the groove 131 at the bottom of the flap body 1 can accommodate sand or debris on the ground or the fixing seat 22, so that the flap assembly can be lowered into place without being affected.

[0086] In this embodiment, refer to Figure 2 and Figure 3 As shown, the flap assembly further includes an end cap 16, and the end cap 16 is disposed at the end of the flap body 1. A protruding connection portion 161 is disposed on the side of the end cap 16 facing the cavity 11, and the protruding connection portion 161 is used to extend into the cavity 11 to fix the end cap 16 to the flap body 1.

[0087] Based on this structure, the shape of the longitudinal section of the protruding connection part 161 is adapted to the shape of the longitudinal section of the flap body 1, and the protruding connection part 161 can be snapped into the cavity 11. In addition, locking members such as screws can be sequentially passed through the flap body 1 and the protruding connection part 161 to lock and connect the end cover 16 to the end of the flap body 1.

[0088] When the pressure plate 12 of the flap body 1 is subjected to the pressure of the vehicle, the pressure plate 12 is supported by the support frame 14 in the cavity 11, and the end cover 16 can support the pressure plate 12 through the protruding connection portion 161. In addition, the bottom of the end cover 16 can be arranged flush with the bottom of the flap body 1, so that the end cover 16 can support the flap body 1 together with the support plate 13 of the flap body 1, thereby enhancing the strength of the flap body 1.

[0089] Embodiment 2

[0090] Different from the first embodiment, this embodiment discloses a parking lock 2. Figure 4 and Figure 5 The parking lock 2 includes a fixed seat 22 and the flap assembly in the first embodiment, and the flap assembly is rotatably connected to the fixed seat 22 via a rotating shaft.

[0091] Specifically, a second mounting hole 17 is provided on one side of the flap body 1, and the rotating shaft is installed in the second mounting hole 17. Figure 4The end of the flap assembly away from the second mounting hole 17 can be away from the fixing seat 22 during the rotation process, so that the flap assembly is used in an open state. At this time, the parking lock 2 is in a locked state of locking the parking space, and the parking lock 2 can prevent the vehicle from entering or exiting the parking space through the flap assembly. Figure 5 When the end of the flap assembly away from the second mounting hole 17 approaches the fixing seat 22 during the rotation process, the flap assembly is used in a closed state. At this time, the parking lock 2 is in an unlocked state to unlock the parking space, and the vehicle can enter or exit the parking space after climbing over the parking lock 2.

[0092] Thus, the parking lock 2 can control the flap assembly to flip, and the flap assembly switches the locking state or the unlocking state of the parking lock 2 during the flipping process.

[0093] Among them, since the cavity 11 is provided in the flap body 1, the overall weight of the flap assembly is relatively light, and the driving assembly 21 can drive the flap assembly to flip using relatively small power, thereby reducing the performance requirements of the driving assembly 21. A support frame 14 is provided in the cavity 11, and the support frame 14 can support the flap body 1 when the vehicle rolls over the parking lock 2, so as to prevent the flap body 1 from sinking, deforming or being damaged.

[0094] More importantly, the support frame 14 extends along the length direction of the flap body 1, which can disperse the pressure of the pressure-bearing surface more, thereby improving the pressure-bearing performance of the flap assembly.

[0095] In addition, a fixing member 24 is provided at the bottom of the fixing seat 22 , and the fixing seat 22 can be fixed relative to the ground by installing the fixing member 24 into the ground.

[0096] In this embodiment, the parking lock 2 also includes a driving component 21. Specifically, the driving component 21 has a driving arm 23, and the driving arm 23 is rotatably connected to the flap component through a driving shaft; when the driving component 21 drives the driving arm 23 to move, the driving arm 23 drives the flap component to rotate around the rotation axis through the driving shaft.

[0097] On this structural basis, a first mounting hole 15 is provided on the flap body 1, and the drive shaft is installed in the first mounting hole 15. That is, the flap body 1 is rotatably connected to the fixing seat 22 via the rotating shaft, and rotates relative to the rotating shaft under the drive of the driving arm 23. Specifically, the driving assembly 21 also includes a driving motor, and the output shaft of the driving motor is connected to the driving arm 23 via a screw transmission member, and the screw transmission member can convert the rotational motion of the motor output shaft into the forward and backward motion of the driving arm 23. Then the driving arm 23 can drive the flap assembly to rotate around the rotating shaft to achieve flipping.

[0098] Among them, the central axis of the first mounting hole 15 is parallel to the central axis of the second mounting hole 17. Therefore, after the rotating shaft and the driving arm 23 are respectively installed in the second mounting hole 17 and the first mounting hole 15, the central axes of the rotating shaft and the driving arm 23 are also parallel to each other.

[0099] Therefore, the flap body 1 divides the cavity 11 into multiple cavity segments through the supporting frame 14, and two of the cavity segments are circular, thereby forming a first mounting hole 15 and a second mounting hole 17, which can provide installation space for the rotating shaft and the driving arm 23; it can not only make full use of the space of the flap body 1, but also reduce the overall volume of the flap body 1 and realize the flipping movement of the flap body 1.

[0100] In addition, when the rotating shaft is connected to the fixing seat 22, the fixing seat 22 can also provide certain support for the flap assembly, thereby improving the pressure-bearing strength of the flap assembly.

[0101] The technical means disclosed in the solution of the utility model are not limited to the technical means disclosed in the above-mentioned implementation mode, but also include technical solutions composed of any combination of the above technical features. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the utility model, and these improvements and modifications are also regarded as the protection scope of the utility model.
